LONGi Solar 445W Hi-MoX6 HPBC Mono Solar Module - Black Frame/White Backsheet

• Manufacturer LONGi Solar

The LONGi Solar Hi-MO X6 LR5-54HTH-445M is a premium 445W mono PV module designed for high energy density on residential and light commercial rooftops. Built on LONGi’s HPBC (back-contact) cell technology, it combines strong output with a clean, modern appearance, making it a great option where aesthetics matter as much as performance.

With a rated power of 445W (STC) and module efficiency up to 22.8%, the LR5-54HTH-445M helps installers maximise kWp on limited roof space while keeping layouts tidy thanks to its practical 54-cell (108 half-cell) format. LONGi also specifies a 0 to +3% positive power tolerance, giving extra confidence that modules will meet (or exceed) nameplate ratings in the field.

For long-term reliability, the module comes with a 25-year product warranty and a 25-year linear power warranty. Degradation is rated at less than 1.5% in the first year, then 0.40% per year from years 2–25, supporting strong lifetime yield and predictable performance over time.

It’s engineered for real-world rooftops too: the 30mm anodised aluminium frame and standard size (1722 × 1134 × 30mm) keep handling and mounting straightforward. Environmental protection is strong with an IP68 junction box, a maximum system voltage of DC1500V, and robust mechanical ratings of 5400Pa front load and 2400Pa rear load, plus hail resistance tested to 25mm hail at 23m/s. Altogether, the Hi-MO X6 LR5-54HTH-445M is a well-rounded, installer-friendly module for customers wanting premium looks, high efficiency, and dependable long-term output.
